2006-10-16 Update: 4OSME was a rousing success! Over 165 people attended some 70 talks. The 4OSME proceedings has been published by A K Peters, Ltd (now part of CRC Press).

Several media groups covered 4OSME. See photographs and a trailer from Green Fuse Films' Peabody-award-winning documentary on origami (portions of which were filmed at 4OSME), Between the Folds.

About our logo: the fractal logo image is a real origami shape designed and folded by Ushio Ikegami, who presented a talk on origami fractals at 4OSME. Lucas Garron, who also gave a talk, has created a nice animation of the logo, using the ray-tracing software POV-Ray.


During the last 20 years, there have been 3 highly successful international scientific conferences exploring the interactions between origami, mathematics, and science. Continuing this series, OrigamiUSA, the American national origami society, is pleased to announce The Fourth International Conference on Origami in Science, Mathematics, and Education (4OSME), September 8-10, 2006, at the California Institute of Technology, Pasadena, California, USA.

In 1989, 1994, and 2001 the first three meetings devoted to origami research and applications in mathematics, science, and technology were held in Italy, Japan, and California, respectively. (Click here for information about 3OSME from 2001.) OrigamiUSA is proud to sponsor this fourth such meeting in collaboration with the Department of Mathematics and additional support from the Information Science and Technology Initiative at the California Institute of Technology.

Scope of the Conference

This interdisciplinary conference brings together artists, scientists, technologists, and educators who explore the relationships between folding, art, mathematics, technology, and education.

Features of the Program

Schedule and Presentations

Some 70 contributed papers will be presented as 25-minute talks in concurrent sessions. The complete schedule and abstracts of the contributed papers may be found here.

Key Dates

Important dates are as follows:

Exhibition and Poster Display

Participants are invited to bring origami works and/or informational posters on topics related to origami science, math, and education for display during the meeting. If you would like to have a display area reserved for you, please indicate this when you register.


Online registration for 4OSME is now closed.


In addition to the abstracts, selected extended papers of talks presented at 4OSME and other origami work in math, science, and education have been compiled in a proceedings book for the conference.
